Q nnvrcn non COOLING Lien-ins.

Applicationled April 2G, 1928. Serial No. 271,625.

This invention relates to refrigeration and more particularly to a device for cooling liquids, such as water, placed in a sult- V able receptacle.

a One object of the invention is to provide an apparatus whereby frozen carbonic acid gas may be employed asa cooling medium and thereby eliminate the use of ice and also permit the water to becooled by a medium in capable of being stored in a small receptacle.

Another object of the invention is to cool the water by a medium which will serve not only as a cooling medium for the water but, if so desired, cause the water to be carbonia ated by disposing the out-let end of a pipe leading from the container below the level of water in the water receptacle.

Another object of the invention is to provide a device of this characterr in which a 2o gas container may be easily removed when empty and replaced with a filled container.

Another object of the invention is to permit the cooling apparatus to be` permanently connected with the water receptacle but at an the same time allow the gas container forming part'of the apparatus to be moved upwardly above the normal water level so that an empty container may be removed and a new one substituted without its being necessary for the person changing the containers to dip into the water in order to reach the container.

The invention is illustrated in the accompanying drawings, wherein.

Figure l is a view showing a water receptacle in section and one form of the invention disposed in an operative position in the water receptacle;

Fig. 2 is a similar view showing a modiiied form of the invention, the' frozen gas container being shown in section;

Fig. 3 isa view showing a water receptacle in section and cooling means associated therewith of the type permanently connected with the water receptacle, and

Fig. 4 is a view similar to Fig. 3 illustrating a modified form of water-cooling apparatus.

The water receptacle or container 1 ma `be of any desiredl size and shape and is pre erably provided with a cover 2 for its open upper end. The receptacle is normally filled with water to the level shown and this `water may be removed in any desired manner or drawn out of the receptacle through a suitable outlet spigot. The receptacle or container 3 for the frozen carbonio acid -gas will be of suitable size according to the capacity of the water cooler or receptacle 1 in which it is to be placed and the frozen gas 4 may be placed directly into the con tainer or, if so desired, it may be stored in containers 5 at the place of manufacture, and these containers 5 fitted into the containers 3 by the person supplying the frozen gas to a user. It will be understoodv that if an inner container is employed lit will have a cover 5 formed with one or more openings through, which evaporating gas may escape. The removable cover 6 of the 70 outer container fits tightly thereon and is provided with an outlet neck 7 which passes through an opening formed in the cover and at its inner end is formed with a iiange 8. This stein 7 is externally threaded to receive a securing nut or disk 9, and it will be readily understood that, when the securing nut is screwed tightly into place, the neck will be firmly held in engagement with the cover. lf so desired, the neck may be welded to the cover instead of being secured by the nut 9. It will be understood that the cover 6. has an air-tight fit upon the container or receptacle 3 and an air-tight joint will be provided between the neck and cover in any suitable manner. The frozen carbonio acid gas is of a snow-like consistency which may be molded into the desired shape to it into yeo .and fill the container 3 and if it is desired to provide a quantity at one time which will last a relatively long length of time the frozen gas may be compressed into a silid mass in which state it resembles a cake o ice.

In the form shown in Figs. l and 2, the gas receptacle or container rests upon the bottom of the cooler or Water receptacle and the gas passes through a pipe disposed vertically in the water receptacle. In Fig. 1, the outlet pipe l0 consists of a metal tube which is threaded upon the neck. 7 and extends upwardly above the normal water level of the water receptacle, the tube being then bent, aslshown at 11, so that its free end portion 12 extends downwardly towards the bottom of the water receptacle. This free end portion extends downwardly into the water so that the gas when passing out ofthe pipe must move upwardlyv through the water and', if so desired, perforations 13 may be formed in the \free end portion of the pipe so that the gas will escape in small Ibubbles instead of as a solid mass. By this arrangement the carbonio acid gas as it passes 'upwardly through the water will cause the water to be carbonated and very palatable.

In Fig. 2, the outlet pipe consists of a metal tube 14 which is straight throughout its length and of sufficient length to extend above the normal water level of the water receptacle. This tube carries a collar 15 so that it may be firmly grasped when it is to be screwed onto or off the neck 7 and at its upperend is provided with a T-shaped head 16 which is screwed upon the upper end of the pipe. When this form of outlet pipe is em loyed, the gas passes upwardly through it rom the container and out through the ends of the head 16. The Water will be cooled by the gas expanding 1n the outlet pipe but it will not be carbonated as the gas is not discharged from the pipe below the surface of the water.

When either of the embodiments shown in Figs. 1 and 2 is employed and it is necessary to replace an empty g'as container with a filled one, the operator after removing the cover 2 from the water receptacle grasps the discharge pipe by the portion projecting upwardly above the water and lifts the pipe and container from the cooler. The empty/ container can then be unscrewed or otherwise released from its cover 6 and a filled container applied to the cover. It will, of course, be obvious that, if desired, the pipe may be unscrewed from the neck and a container having a cover applied to it at the place of storage `substituted for the container and cover removed from the pipe. Threaded caps each having a relief opening in its top may be employedto seal the necks of the containers carried by the o erator, and these caps will be removed be ore the neck of a filled container is screwed into a discharge pipe.

In Fig. 3, the discharge ipe 17 also consists of a metal tube w ich is straight throughout its length and at one end the pipe carries an elbow 18 adapted to be screwed into the neck 7 and at its other end the tube is screwed into or otherwise suit-ably engaged with an elbow 19 loosely received in one end of a hollow terminal 20. This terminal 20 has its end op osite from the elbow 19 closed by a remova le plug 21 and is formed With a side extension 22 having a threaded bore communicating with the interior of the shell. The threaded bore of the side arm 22 receives the threaded end of a hollow fastener 23 which is 4passed through an opening formed either in a side wall or the bottom of the water receptacle, and it will be readily understood that, when the fastener is screwed tightly into place with the washers 24 and 25 compressed between the side' arm 22 and annular flange 26 of the fastener, the terminal will be securely held in place and water prevented fromleaking through the opening in the water receptacle. Since the elbow 19 fits loosely in the terminal, the discharge pipe will be pivotally mounted for vertical movement and, therefore, when the chain 27 which is suspended from a hook 28 within the water cooler is drawn upon, the gas container may be drawn upwardly above the water in the cooler, as shown in Fig. 3, where it may be removed and a filled one substi` tuted. After a filled container is set in place, it will sink to the bottom of the water cooler and as the gas passes from the container through the discharge pipe to the terminal and out through the` hollow fastener the water in the cooler orf Water receptacle will be chilled. l

In Fig. 4, the hollow fastener which is indicated by the numeral 29 is )assed through an opening in a side wall o the water receptacle with a washer 30 disposed between the wall of the receptacle and the collar 31 of the fastener and is held in place by a securing nut 32 screwed upon its inner end and bearing against washers 33 and 34 disposed about the fastener. A nipple 35 extends from the inner end of the hollow fastener and fits into one end portion of a discharge pipe 36. This discharge pipe is flexible and preferably formed of rubber. although other materials may be substituted andhas its other endportion fitted upon the neck 7 of the gas container where it may bc held either by its frictional gri with the neck or through the medium o a suitable clamp disposed about it and tightened. When this form of the invention is employed, the gas container may be easily drawn upwardly by the chain 37 which corresponds to the chain 27 and is suspended from a hook 38 and after a filled container has been substituted for an empty one the chain released and the container allowed to sink to the bottom of the water cooler.

I have, therefore, provided avery convenient means whereby frozen carbonio acid gas may be employed as a cooling medium for drinking water. While it is stated that the gas is to be employed to chill drinking water, it will be understood that other liquids may be poured into the receptacle instead of water.
